To all whom it may concern:

Be it known that I, Gnonen A. KERESTES, a citizen of the United States,residing at Pittsburgh, in the county of Allegheny and State ofennsyl'vania, have invented certain new and useful Im rovements inMotion- Picture and Target pparatus, of which the following is aspecification.

My invention relates to improvements in motion picture machines and alsoto motion picture target apparatus of the class employing a target, apicture projecting device, and electrical connections between the targetand projector actuated by the impact of a bullet or projectile on thetarget for automatically stopping the movement of the picture film.

In the employment of motion picture machines, it is desirable at timesto present a still picture on the screen instead of a moving picture,thus, for example, where the moving picture is being utilized inconnection with a lecture or a talk, or more frequently, when the motionpicture machine is being employed in connection with a target apparatuswherein the projecting device is stopped by means actuated by the impactof a bullet or by firing a shot, etc.

Prior to my invention, the stoppage of the picture film in order toproduce the still'picture has been accomplished by stopping all of themoving parts of the machine, the result being that the machine soonbecomes destroyed or inefiicient, due to the sudden stoppa e of itsrapidly moving parts.

n object of the present invention is to provide simple and eflieientmeans for stopping the movement of a picturefilm for the purposes abovedescribed, without affecting or stopping the rapidly moving parts of themachine.

A further object of my invention is to provide a new and improved motionpicture target apparatus. a

In the accompanying drawings which illustrate an application of myinvention,

Figure 1 is a rear elevational view of a motion picture machineembodying my inlower one being the intermittently driven to beprojected; and C .a target or back wall. 1

The moving picture machine, as illustrated, includes a casing 1 of anysuitable construction, the lens 2', and a shutter 3. As shown,the'movable parts are drlven by means of an electric motor 4, althoughthe machine may be'operated manually. The main drive shaft 5 isconnected with the motor by means of a belt 6 and drive wheel 7. 8designates a fly wheel mounted on shaft 5. The film tape 9 is designedto be fed down through the machine from reel 10, over opening 11 offrame 12, in the usual manner.

The filmpasses over and is fed through the machine by the feed wheels orsprockets 13 mounted on a shaft 14, and the usual intermittently drivenwheels or sprockets 15, the latter being mounted on shaft 16. Shaft 14is driven from the main drive shaft 5 through gearing 17 and 18 and theshaft 16 is also driven from shaft 5. The means illustrated for drivingthe intermittently driven shaft 16 include a star wheel 19, of theGeneva type, mounted on and keyed to the shaft 16, a shiftable sleeveelement 20 carrying a pin 21 and having a clearance space 22 for thestar wheel and a groove 23, said element 20 being mounted and slidableon drive shaft 5. The shutter 3, as illustrated, is drivenfrom shaft 5by means of gearing 24.

The elements above described, with the exception of the shiftable sleeveelement 20,

are of known construction and are arranged to operate a mot on picturemachlne 1n the usual manner. It should also be understood that myinvention is not limited to the combination of these elements with meansfor arresting the movement of the film without stopping the motorand'the rapldlymoving parts of the machine, for my invention may beembodied in motion plcture machines having mechanism differingconsiderably from that shown.

A characteristic and important feature of my invention is the provisionof means cooperating with the intermittently driven film feed wheel orsprocket, or sald wheel or sprocket and the other film feed wheel orsprocket of a motion picture machine, whereby the movement of the filmthrough the machine may be stopped for a desired perlod of time withoutstopping or affecting the other movable parts of the machine.

The mechanism employed for stopping the rotation of the intermittentlydriven shaft 16 or the feed wheels or sprockets 13, in addition to theelement 20, includes a.

' movable bent downwardly extending arm 25,

pivotally secured to the framework of the machine with its fulcrum pointat 26. Arm 25 carries a pin 27, the latter being entered in the groove23 of element 20; the lower portion of the arm is bent as shown at 28,and said portion 28 is formed with a flange or bent up portion 29. 3Odesignates a stop element mounted on shaft 5, the function of which isto prevent an inward movement of arm 25 and the consequent shifting ofelement 20 until the desired instant. That is to say, the element 20should be permitted to slide only when a complete picture is shown onthe screen. Said stop element 30 is formed with a collar 31 having alattera-lly extending slot 32 through which the flange 29 of arm 25 maypass to permit the inward movement of said arm and element 20. Themovement of arm 25 is effected by a horizontally extending rod 33 havingone end attached to arm 25 at 34 and its opposite end connected with alink 35, the latter being pivotally secured to a portion of the frame.

As illustrated and as preferred, the movement of the rod 33 is effectedby means of a bar 36 connected with and adapted to be moved by the core37 of a solenoid 38; and for this purposebar 36 is provided with a pin39 entered in the pivotally mounted link 35. It is evident, however,that bar 36 may be moved by other than electrical means.

For the purpose of stopping the rotation of the feed sprockets 13 onshaft 14, when desired, I provide a clutch mechanism 40. Said clutchmechanism, as shown, is operated by means of the bar 36, a pivotallysupported link 41-secured at 42 to the frame, a rod 43 extending fromthe link to the clultcch, and a pin 44 coiiperating with the lin Theparts just described are particularly illustrated in the detail view ofFig. 3, and as there shown, are arranged to drive the film feed wheels.An upward movement of the bar 36 will release the clutch mechanism 40and also shift the slidable element 20, thereby throwing pin 21 free ofthe star wheel 19 as the former revolves with the element 20. A movementof the bar 36 in the opposite direction or into the position shown byFig. 3 will permit the film to be fed through the machine, with theusual intermittent movement.

. The mechanism herein described provides simple and efficient means forautomatically stopping for a predetermined period the movement of thefilm, thereby enabling a still picture to be shown on the screen, thisbeing accomplished without stopping the other movable parts of themotion picture machine.

In the present invention I have shown the motion picture machine and theabove described means for stopping the picture film in connection with atarget apparatus and electrically operated means between the taret andthe machine designed to be operated 5y the impact of a bullet orprojectile on the target.

The target structure 45 is similar to the target structure shown in an aplication filed by me December 18, 1918, erial No. 267,341. As shownherein, it includes a plurality of loosely suspended impact plates 46,said plates being suspended from rods 47 and adapted to be movedinwardly the desired distance by the impact of a bullet. Each plate isprovided with a push rod 48 adapted to strike against an angle plate 49,the latter being mounted on a tilting bar 50. Bars 50 also carry avertical row of plates 51 having divided ends adapted to straddle avertically movable switch actuating rod 52. Rod 52 is providedwith aseries of pins 53 which engage the divided ends of plates 51. It will beunderstood that an inward movement of an impact plate will tilt a bar50, and that when this occurs, the switch actuating rod 52 will beraised. Raising the rod is designed to complete an electric circuit forthe purpose of efi'ecting certain operations hereinafter described.

In the embodiment of my invention as shown by the drawings, theelectrical current employed in connection with the various parts of theapparatus is obtained from the main line 60.

An upward movement of the switch actuating rod 52 caused by the impactof a bullet against one of the plates 46, acting through the means abovedescribed, will operate a toggle arm 61 pivotally secured to an arm 62of the frame. Toggle arm 61 engages the lower end of rod 52, and, uponthe upward movement of said rod, arm 63 of toggle 61 is moved to makecontact with an enlarged portion 64 disposed at the lower' end of apivotally mounted curved arm 65.

' tact strip of the switch mechanism and 70 a movable switch armdesigned to be thrown by the movement of the horizontally movable arm67. The connection between the.

arm 67 and the switch arm 70 includes a pivotally mounted arm 71 securedat 72 to the frame of the machine and pivotally connected with arm 67 bya pin 73. Arm

71 at its upper end is provided with a pin 7 41- adapted to operate in aslot 75 of the switch arm 70. As shown, a movement of bar 67 to the leftwill cause switch arm to move from stop block 69 to contact point 68,thereby completing an electric circuit to solenoid 38 of the motionpicture machine, and at the same time completing an electric circuit toa motor 76 of the timing mechanism.

The timing'mechanism includes, in addition to the motor, motor shaft 77having a worm 78 thereon, a pinion wheel 79 meshing with said worm, astriking pin 80 carried on the pinion, a pivoted arm 81 having its endsdivided and engaging a pin passed through arm 67, and a .pivotallymounted arm 82 secured to the divided arm 81.

' It will be understood that the closing of the circuit 90 leading tosolenoid '38 energizes the core 37 of the said solenoid to raise thebar'36, thereby throwing out the clutch mechanism 40 and moving theslidable element 20 on drive shaft 5 to disconnect said element from thestar wheel carried on the intermittently driven shaft 16, thus stoppingthe film feed wheels 13 and 15. The time the movement of the film isarrested depends upon the speed of rotation of the wheel7 9. It will beunderstood that with the closing of the circuit 90 to the solenoid 38 acircuit 91 is completed to the motor 76, thereby starting said motor andthe timing-mechanism.

The speed of the motor is controlled by means of a regulator 92. Fromthe drawings and a reference to the companion application abovementioned, it will be understood that the period of rest of the filmwill depend on the time it takes forthe striking pin 80 to make arevolution, for it will,

be noted that upon each revolution of striking pin 80 said pin will comeinto contact with rod 82, thereby causing the switch arm 70 to bebrought from engagement with contact point 68 into engagement with stopblock 69.

For the purpose of moving the screen or curtain B, I provide a solenoid93, the core 94 of which is employed for moving a dog 95 on a ratchetwheel 96 mounted on the shaft of the screen reel. The circuit 97 forsolenoid 93 is also made and broken by means of the striking pin 80 onpinion 79. This is effected by employing a pivotally mounted switch arm98 adapted to be moved into contact with contact plate 99.

100 designates a movable shutter preferably made of colored mica, thisshutter being adapted to be moved over and away from the opening 11 (seeFig. l) by the movement of the bar 36 and the connections between saidbar and shutter. Said connections include a toggle arm 101 carrying apin 102, a pivotally mounted plate 103, the latter having a slottedportion 104: into which the pin 102 is entered. The function of theshutter 100 is to change the color of the picture thrown onto the screenduring the time the movement of the film is arrested. It will beunderstood that the shutter may be omitted if desired, although I findit of advantage for the purpose of enabling the bullet holes made in'thescreen B to be more readily seen, and also this shutter greatlydiminishes the heat generated by the light ra s.
